Thomas Edison A Brief Biography of a Genius Essay

Thomas Alva Edison was born on February 11, 1847 in Milan, Ohio. He was named Thomas after his father’s brother and Alva after his father’s friend Captain Alva Bradley. His family called him Al. Al was a handful. He was very curious about a group of large grain elevators; he once fell in and disappeared under the grain. He was pulled out before he suffocated. Al also fell in the Milan creek many times. One time Al was found trying to hatch a handful of chicken and goose eggs on a nest of his own that he made. Al was really curious about a nearby work shop owned by a man named Sam Winchester. The town’s people called Sam the â€Å"Mad Miller of Milan†. Winchester was rejecting his flour milling business to make a passenger balloon which his†¦show more content†¦If Al wasn’t doing experiments he was reading. He would check out books at the Detroit library. While watching the trains at the Mount Clemens station, he saved a three year old boy. He was the son of the lead telegrapher who taught Al his trade. By age eighteen he was a second degree telegrapher, which let him travel to other places. At this time he started calling himself Tom. He often got in trouble and got fired, but he always found a new job. Tom kept on moving and learning. He soon became one of the best telegraphers. He decided to move to Boston, the center of science. He worked at Western Union. He started learning finance and what it would take to back an invention. In 1868 he signed his first patent for a vote counter. At age 22 and with no money Tom moved to New York. He accidently got a job at the Gold Indicator Company. He improved the company so much that Western Union bought them out. Tom got investors so he could start inventing. When he sold his first patent for $25,000 he split his partnership so he could keep all the money. Tom was making more money than he knew what to do with; he had to learn how to bank. Then his mother died so he threw himself into work. He started a factory that went from eighteen to one-hundred and fifty people; that’s where he met Mary, his first wife. They had three kids named Marion, Tom Jr., and Will.

The Great War Of The World War I - 2497 Words

A dilemma that was happening for many years can be resolved, but there will be disadvantages and advantages ,no matter what the outcome is. The Great War also called the World War I , started on July 28, 1914 in Europe.The war lasted for four years to end all wars that happened before involving other countries. From beginning to end of the four years, men were not the only ones working hard, so were women. When men went to fight in the war, it led to major grasps in the labor market, so industries and the government reached out to women and asked them to volunteer in specific jobs that were hiring. However the paying jobs did not mention to women that the high wage jobs were temporary.The government used a sneaky tactic on women in order†¦show more content†¦It led men to be involved in riots and protests against women to work in labor market where the government ordered women to go back to their old jobs or back to being unemployed. This problem led women to be involved in protests and women did not have equal rights compared to men ,so they created suffrage movements. Immigrants at the time came to America to find work and some were involved in suffrage movements but it was a disadvantage for women that worked in industries, because it was cheaper to hire an immigrant than a women in the United States. However immigrants were involved in helping throughout the protests and suffrage movements, that was a huge advantage for people to hear about their movements. Women, immigrants and also African American women were involved in the suffrage movements. African American women volunteered to do suffrage movements because they were paid less than a white person,wanted to be recognized and their goal was to have equal rights so they can have the same education as men.â€Å"Night work for women today with their dual capacity as wage-earners and homemakers means burning the candle at both ends with very little sleep, much overwork, fatigue, and the coming of old age unnecessarily soon(U.S Women’s Bureau,1930). Says that women work so hard toward the goal, overdoing it that it makes them not live life longer and
